Ign.com has released a preview for Rise of Legends, the sequel to Rise of Nations. The preview covers the Alim nation and its many units and buildings. Here's a small sample of Alim building varieties:

* Desert Walker: The Desert Walker is the basic Alim foot soldier. Desert Walkers are the foundation of the Alim army and are feared for their ability to attack with ruthless aggression and disregard for personal safety.

* Scorpion: This beast of the dunes has been domesticated and bred by the Alim for centuries. Occurring in nature to a size of about four feet high, the Alim have bred for speed, size, and power, and now command hordes of Scorpions that stand nearly seven feet high and whose pincers can snap swords in two.

Although the Macintosh version hasn't been announced yet, Rise of Nations was ported to Macintosh, and Rise of Legends seems a likely candidate to follow.
